CHAPIN C. BROOKS, OF \VILTON, MAINE.

MAGAZiNE sour-eon $PECIFICATION forming part of Letters Patent No.726,251, dated April 28, 1903. Application filed July 20,1899. SerialNo. 724,550. (No model.)

To all whom it may concern:

Be it known that l, CHAPIN O. BROOKS, a citizen of the United States,residing at Wilton, in the county of Franklin and State of Maine, haveinvented a certain new and useful Improvement in Bolt Magazine-GL1 ns;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to bolt magazine-guns; and it consists in animproved frame, an improved breech-bolt, an improved means of operatingthe same, and an improvement in the means for controlling the magazinesand feeding the cartridges from the latter iuto the gun.

In the drawings, Figure 1 is a side eleva the frame and the right-handmagazine being removed, the barrel being shown in vertical longitudinalsection. Fig. 2 is a vertical longitudinal section of the breech-bolt,the firing-pin being retracted, as when the gun is cooked. Fig. 3 is avertical transverse section of the magazine, showing cartridges in positon and the breech-bolt closed. Fig. 4 is a vertical transverse sectionof the breech- Fig. 5 is a bottom plan of the arm which operates thedevice which controls the magazines and the arms 0 0. Fig. 6 is a sideelevation of the frame, with part of. the frame and cover of themagazine broken away. Fig. 7 is a top plan of part of the frame andbreech- Fig. 8 is an elevation of the outer side of the cam-lever A.Fig. 9 is a transverse horizontal section of the rear part of themagazines and of the mechanism controlling the movement of thecartridges, and Fig. 10 is a side elevation of the inner side of thecan1-lever with adj-ac out part of the frame.

Referring to the drawings, a represents the frame, I) the barrel, and cthe breech-bolt.

The frame a is shown in Figs. 1, 3, 6, and 7. It has a flattened topwith curved sides. In the top is a rectangular longitudinal slot 6",which extends backward from the rear of the barrel to the rear of themagazine, having a bridge or tie. 7 between the slot 6 and the rear ofthe frame, as seen in Fig. 7. The rear of the frame has a slight slot toreceive the rear end of the breech-bolt, while the right side of thecurved wall is elongated into the ear 5. (See Fig. 7.) On the inner sideof this ear is a stud l4.

The construction of the breech-bolt c is shown in detail in Fig. 2. Ithas the usual cartridge-retractor d, a spring-actuated firingpinf, and acartridge-ejectorj, actuated by the spring 7c,while e is thecocking-head of the firing-pin. Near the rear end of'the breechbolt is arecess 8 in its upper surface, which receives the bridge 7 of the frame.Fixed to the under side of the breech-bolt beneath the extractor is thepiece m, the lower outer edges of which are provided with flanges m Thecocking-head has on the right-hand side a spring-actuated dog 7, infront of which on the same side is a projection 9, having in its forwardsurface a semicircular recess 10. Upon the under side the cocking-headis provided with a notch a. to receive the sear p. The rear end of thebreech-bolt is provided with a circular transverse perforation 4, directly in front of which on the right-hand side is a pin 6. The officeof the perforation i is to receive the stud 13 of the cam-lever A. Theinner or left-hand surface of the cam-le ver A, as seen in Fig. 1, hasupon its surface directly beneath the stud 13 a stud 12, while at therear of the lower edge is another stud 11. The outside of the cam-leverA is provided with a recess 15, which terminates at the lower end in acurve. (See Fig. 8.) This recess is designed to receive the stud 14:,already described. (See Fig. 7.)

The magazines, which are located on either side of the gun, are ofsimilar construction and are provided with carrier-arms 2 and fingers 3,pivoted at their'rear ends to the ends of the carrier-arms 2.andactuated by springs 4, respectively, as seen in Fig. 6. Each carrier-armhas its lifting-spring to raise it and its superimposed cartridges. Theconstruction of the magazines and their location with reference to thebreech-bolt are shown in Fig. 3, 02. n being the inner walls thereof,termihating at the top in the flanges m m, and n or are the doors orcovers.

Themechanism for advancing and throwing the cartridges in front of thebreech-bolt 0 when the latter is retracted is situated in the rear ornear the rearof the cartridge boxes or hat dhasabout mlwaq;

lma'm' magazn e N the ins 1 when the gun has been fired five times ormore, the right-hand magazine becomes ex hausted and it is necessary torefill the righthand magazine or draw upon the left-hand magazine. Theleft-hand magazine has hitherto been locked, and it it is desired todraw upon it it is necessary to push forward the button 13 on the leverZ, whioh has the eftect by reason of the play of the pin at in theoblique slot 2 in the lever Z to carry the shaft 1' into the slot 3 inthe left-hand cam-lever 8. The left-hand magazine is thus called intoaction, as the right-hand cam-lever 8 no longer operates and thefunction performed by it heretofore is consequently performed by thelefthand cam-lever l. The forward end of the breech-bolt as it isretracted and returned slides upon the flanges m m of the walls n n ofthe magazines, the flanges m of the piece m keeping it in position. Thebreech-bolt may be further guided in its movement into and from itsrecess in the breech-bolt opening by a flange or similar means attachedto the frame in the rear of the breech-bolt when closed and adapted toenter the longitudinal groove 6 in the breech-bolt.

\Vhat I claim is- 1. In a gun, the combination ot-movable arms and adepressible retractable breechbolt, the latter provided with alongimldinal groove adapted to receive projections upon the inner sidesof the former and a sear pivoted between and carried by said arms,substantially as described.

2. In a gun, the combination of a breechbolt having a spring-actuatedfiring-pin and cocking-head with a cam-lever whereby the breech-boltmaybe depressed from its recess in the frame and retracted and meanswhereby the cocking-head may be partially retracted when said bolt isdepressed, substantially as described.

3. In a gun, the combination of a breechbolt having a spring-actuatedfiring-pin and cocking-head, a cam-lever whereby the fi ing pin may berel racted in the breech-bolt while the breech-bolt is being depressedand means whereby said lever and said firing-pin may be locked when thefiring-pin has been retracted as aforesaid, substantially as described.

4:. In a gun, the combination with a breech bolt having aspring-actuated firing-pin and cocking-head,a cam-lever whereby thebreechbolt may be first depressed and then retracted from its recess inthe frame and then returned and elevated in said recess and means forlocking said lever while said bolt is depressed, substantially asdescribed.

5. In a gun, the combination of movable arms and a depressibleretractable breechbolt, the latter provided with a longitudinal grooveor grooves adapted to receive projections on the inner sides of theformer, magazine or magazines at the side of the breech and means,operated by the movement of said arms, whereby the uppermost cartridgeof the magazine is advanced ready for deliveryinto the receiver,substantially as described.

6. In a gun provided with a magazine on each side of the breech-bolt,means for feeding from either of said magazines actuated by thewithdrawal of said bolt, substantially as described.

7. In a gun provided with a magazine on each side of the breech-bolt,means for feeding from either of said magazines actuated by v thedepression and withdrawal of said bolt and means for connecting saidoperative mechanism with either magazine, substantially as described.

S. In a gun provided with a magazine at'the side of the breech-bolt,means for holding the uppermost cartridge in said magazine until thebreech-bolt is depressed,and means whereby the said cartridge isreleased by the depression of said bolt and advanced along the side ofthe breech-bolt whence upon with drawal of said bolt it enters thereceiver, sub-' stantially as described.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand this 15th day of July, A. D. 1899.
